PENDANT-SET WATCH.

SPECIFICATION forming part of Letters Patent No. 447,474, dated March 3,1891.

Application filed September 8,1890. Serial No. 364,273. (No model.)

To all whom it may concern.-

Be it known that LRoswELL L. PEABODY, a citizen of the United States,residing in the city and county of New York, in the State of New York,have invented a certain new and useful Improvement in Pendant findingand Setting lVatches, of which the following is a specification.

I have devised an improved mechanism simple in construction andthoroughly reliable in its action, adapted to apply to all that class ofwatches having provisions for shifting or changing the winding andsetting work from one condition to the other by an endwise movement ofthe winding-stem. It is equally well adapted to hunting-case or openfacewatches. I have the ordinary provisions of the hunting-case forliberating the cover by thrusting inward on the crown, and therebymoving the stem longitudinally inward to a sufficient extent to cause itto release a strong catch, the ordinary holding-spring allowing thecover to fly open, and I have the ordinary provisions of thependant-setting watch for adjusting the parts for setting by simplypulling outward on the crown and thereby temporarily disconnecting thewinding mechanism and connecting the setting mechanism. I provide apartially-revolving piece, which I term a cam and an operating-levertherefor, both interposed between the yoke and stem. These parts arearranged to allowalarge amount of idle motion. hen the stem is thrustinward and allowed to be returned to effect the frequently-recurringopening and closing motions of the huntingcase, the lever and connectedcams swing idly through the small are required. \Vhen the stem istemporarily drawn outward, these parts are set at liberty, and areoperated by a spring to reliably shift and hold the yoke in position forsetting the hands. I have devised an improvement in the yoke, wherebythe arm which operates it is bent downward and affords a wide bearing,against which a thin intermediate cam sunk to a lower plane may workwithout risk of slipping past until the yoke is moved in position forsetting the hands. I have devised a lever having a bearing endcorrespondingly bent down, which affords a broad bearing against theoperating-collar on the winding-stem.

The accompanying drawings form a part of this specification, andrepresent what I consider the best means of carrying out the invention.

' Figures 1, 2, and 3 are face views with certain portions removed. Fig.1 shows the mechanism in condition forwinding. This is the condition inwhich the watch is ordinarily maintained. Fig. 2 is partly in sec tion.It shows the crown drawn out to put the mechanism in condition forsetting. Fig. 3 shows the crown pressed inward to lib-v erate the cover.Fig. 4: is an edge view of the watch, partly in section. It shows themechanism in the same condition as in Fig.

l. The remaining figures are on a larger scale. Fig. 5 is across-section. It shows an edge view of the arm of the yoke with its endbent down, and a section of the adjacent part of what I term the cam.Fig. 6 is a corresponding cross-section of another portion of the watch.It shows an end view of the internal stem, sometimes called thesnap-stem, viewed from the interior of the watch, andan edge view of thelever, the end of which is bent down and pressed against a collar on thestem. Fig. 7 is a view of the stem and loose collar thereon and of thewinding-pinion carried on its extreme inner end.

Similar letters of reference indicate corresponding parts in all thefigures where they appear. 7

A is the stationary casing of the watch, certain parts being designated,when necessary, by additional numbers, as A A The pendant A, the bow N,the cover 13, and the catch C, which holds the cover, may be all of theordinaryand long-approved construction.

D is the snap-stem, an internal stem fitting in the pendant, withliberty to be revolved by acting on the ordinary crown outside, and alsoto be pressed or thrust inward against the force of a strong spring 0and to be drawn forcibly outward to the proper limited extent to adjustthe watch for setting. The stem is provided, as usual, with a collar D,which receives springs E, set in the pendant, which serve to hold thestem alternatively in the two conditions with regard to setting andwinding-that is to say, when the stem is forcibly drawn outward thecollarD' is moved outward past the point of bearing of the IOC springsE, and is retained in the outward po sition so long as is required toset the watch. 'WVhen this has been carefully completed, the stem mustbe thrust inward again by a .sufficient pressure on the crown to carrythe collar D inward past the springs E, and thence forward the springsserve to hold the stem inward.

G is a yoke which carries the gearing which in one position engages withthe geanwheel H, only a part of which is shown, and effects the winding,and in another position engages with the cannon-pinion I, which is onthe central arbor and effects the setting. an arm thereon which extendsradially outward and is bent downward at a right angle, extending into asufficient recess to be presently described. It is acted on by a springJ, tending to hold the yoke always in position for winding, except whenit is acted on by a sufficient force to throw it into the oppositeposition.

K is a partially-rotating plate, which I term a cam, sunk in a recess inthe pillar-plate of suitable area and form to allow it a wide range ofmotion. It is pivoted on a screw 70 and performs important functions.Its edge K is adapted to act as a lifting-plane against the arm G of theyoke G, and moves the latter into position for setting the hands. Theentire cam is subject to the force of a spring L, which presses againsta pin K and tends constantly to turn the cam in one direction.

M isa lever turning on a fixed pivot m on the front of the pillar-plate.Its long arm receives from a pin K in the cam K the force of the springL. The other, the short arm of the lever M, is bent downward at rightangles, extending through a sufficient hole provided in thepillar-plate, as shown by M in Fig. 6. This bent end affords a largehearing which is pressed against a collar D on the stem D. This collarcontrols the position of the cam K. While it stands in the positionshown in Fig. 1 it holds the lever M in such position that its contactwith the pin K holds the cam K idle. When, on the contrary, the stem Dis drawn forcibly outward, so that the springs E snap over the collar D,this change of position of the collar D sets the lever M at liberty, andit relaxes its resistance to the pressure of the pin K Then the springL, acting on the pin K turns the cam K, and thereby turns the yoke Ginto the position shown in Fig. 2, and rigidly holds it there by reasonof the cam K having turned so far that its angle presses the bent arm G.Now the latter rests on the small section 70' of the cam K,

. which may be concentric to the center of the yoke G and the spring Jturns the yoke into the position for winding, which is the originalposition, that shown in Fig. 1.

O is the ordinary stout catch or spring-head which engages and releasesthe cover B of the watch-case. This is important when the case is ahunting-case. The catch is traversed by the stem D, and is subject tothe action of a shoulder D thereon. The stem D is free to be pushedinward to the extent'necessary to actuate this catch. The squaredportion on the inner end of the stem D is of snfficient length to allowthe stem to move endwise in the correspondingly-squared hole in thewinding-pinion. There is provision by a sufficient space under the crownand at the engagement with the springs 'E for such mo-,

tion of the stem.

The form of the lever M and cam K and the arrangement of theirrespective centers allow provision for the-motion given to thelever Mand to the connected cam K, these parts M and K swinging or partiallyrevolving idly in their respective places at each opening and closing ofthe watch. The cam K difiers from ordinary devices for this purpose inhaving the lifting-plane K wholly on the cam, instead of mostly orwholly on the yoke. Sinking the cam below the plane of the yoke avoidsthe action of thin edges on each other in the same plane or parallel,thereby avoiding risk of slipping off and getting much better results.

All the parts are made to gages and are interchangeable. This allows theWorks to be transferred from one case to another.

With the winding work in its normal position, Fig. 1, the crown has beenpushed home on the pendant, carrying with it the windingstem D, thecollar D which forces the bent end of the lever M toward the center ofthe watch, causing the opposite end of this lever toact on the pin orstud K and swing the cam K away from the arm G of the yoke G, and hasallowed the latter to turn by the force of the spring J and assume theposition for winding. Drawing the crown forcibly outward allows thecollar D .to recede and relieves the pressure of the lever M on the studK and the spring L, acting on the stud K swings the cam K so that itsstraight edge K comes in contact with the arm G of the yoke,

turning the latter into position to engage the setting-wheels with thecannon-pinion or with a connected wheel ready for setting the hands.Releasing the crown and forcing it inward again operates the lever M toturn the cam K again into the idle position, and the yoke G is againforced by the gentle spring J into the position for winding. In closingthe cover the catch 0 is operated and the cam K is turned idly. When-atany future period the crown is pressed inward to a sufficient extent,this catch 0 will be operated, and if the case is a hunting-case this isthe proper movement to effect the opening of the case. It has no effecton the yoke G and its connections.

My invention serves well with huntingcases, a desideratum heretoforeunattained in mechanisms of this character for watches that areinterchangeable from one case to another.

Modifications may be made without departing from the principle orsacrificing the ad vantages of the invention. Instead of bending themetal of the arm G, the metal may be finished straight and a pininserted reaching downward to the same extent.

setting mechanism and having the bent arm G and actuating-spring J, incombination with the cam K and spring L, acting on the stud 1 and withthe lever M M and the stem D, having the collar D and arranged to bemoved endwise as well as rotated, as set forth.

3. In a stem winding and setting watch, a pull-stein I) D, a spring-headC, operated by thrusting the stem and adapting the mechanism to serve ina hunting-case, and the lever M, cam K, intermediate between the leverand the yoke, said cam carrying the pins K and K and theactuating-spring L, in combination with each other and with the yoke Gand its operating-spring J and the gearing for winding and setting, allarranged to serve substantially as herein specified.

In testimony that I claim the invention above set forth I affix mysignature in presence of two witnesses.
